Afternoon all! I have a 13,500 A/C unit in my trailer. The trailer power is 30amp. Is it safe to run my trailers A/C on the 115V 15amp supply at the trailer storage place? I don't want to run it for long periods of time, only an hour or so if I have to do work on the trailer while it's parked there. (I live in TX and it's HOT!!!). Thanks in advance for any help!

That really is probably not enough amps! Unless of course when you turn it on the first time and it doesn't blow the breaker, make sure to have it on its very coldest setting so the compressor never goes off. Then it would probably work. That is what I do when power is scarce and it works for me. It takes something like 2 to 4 times the power to start that compressor that to keep it running. JMHOAlso I think they say below 110 volts you may be damaging you AC. I ain't no electrician so we can wait for some professional advice here shortly.

I do it here all the time here with our 13,500 BTU Air Conditioner on a separate 20AMP circuit from my garage. My POPUP Trailer is a good 50-feet away from the garage in the back yard and I use a 50-foot 10-3 HD Extension cord and a RV30A-15A 'LONG Dogbone' type adapter from WALMART... The 10-3 contractor type HD Extension cords are expensive but I was able to find a couple for sale at a yard sale. You might be able to talk a local RV DEALERSHIP out of a couple of used long extension cords for a good price... When I bought my trailer they passed-on one to me for the asking... These were M/F RV30A cables.We always watch what else is on in the trailer and don't have any problems getting any connections hot outside or tripping any breakers in the garage...Roy Ken

I wouldn't - risky - with possibility of damage to the compressor ...and for sure you will not be able run anything else at the same time.If you try it, hopefully the circuit will pop before any damage.20a yes.
